BRIEF SUMMARY

In view of the above-mentioned prior art, the disclosure provides awater slide system including at least one slide tube section via whichthe slide experience for the user is improved by implementing elaborateoptical effects. The aim in particular is to provide the water slidesystem in such a way that the subjective feeling of acceleration orsliding speed and/or a feeling of direction are/is influenceable.Moreover, the system may provide a method for operating such a waterslide system.

In an aspect, the lighting features are formed from pixels, which mayinclude LEDs, for example, arranged in a matrix of at least one screenmodule (LED module or digital image area), which in turn is arrangedand/or designed in the manner of a shell on the outer side of the slidetube and extending over a circumferential section of the slide tube, andwhich is actuatable and/or actuated in order to display, for example,moving two-dimensional and/or stereoscopic images that are curved in thecircumferential direction.

In an aspect, a water slide is designed, at least in sections, as ascreen slide, i.e., in such a way that two-dimensional and/orstereoscopic, preferably moving, images that are curved in thecircumferential direction of the slide tube are displayable from theinterior of the slide tube, i.e., are visible to a user when sliding,via which, for example, the subjective feeling of acceleration and/orvelocity and/or slide direction of the user may be influenced. As aresult of an image that is uniform or repeating, or which moves orshifts opposite the slide direction, for example in the form of movingarrows or the like, in particular over a time period of several seconds,it is thus possible to achieve an impression of speed that is greaterthan the actual sliding speed. Additionally or alternatively, it ispossible to display visually changing light and/or color effects in theform of two-dimensional and/or stereoscopic stationary images or videos(images moving in two dimensions and/or stereoscopically). In oneaspect, the image may extend over a circumferential angle of at least120°, preferably at least 180°, and/or over a length of at least onemeter, particularly preferably over at least five meters, even morepreferably over at least 10 meters or longer, in the slide direction.The resolution of a screen module may be preferably at least 100×100pixels, and more preferably 250×250 pixels. In an aspect, multiplescreen modules having such a resolution may be provided, for example,next to one another in the circumferential direction and one behind theother in the slide direction. The screen modules may be actuated in sucha way that an overall image is displayable with the screen modules, forwhich purpose the multiple screen modules are connected, preferably in asignal-conducting manner, to a so-called video splitter that divides anoverall image over the multiple screen modules, i.e., into partial imagesections.

As the result of images moving in the circumferential direction, it isadditionally or alternatively possible to create a subjective turningdevice pressure that suggests to the user that he/she is moving in thecircumferential direction, i.e., to the right or left. It is alsopossible to impart the subjective impression of a slower sliding speedby moving image content in the slide direction. To achieve this effect,identical or similar image contents are preferably selected, at leastover a certain time period, which progress from pixel to pixel in thedesired direction, i.e., appropriately moved forward by actuatingfeatures on a screen module and preferably shifted from screen module toscreen module.

In order for a sharp image to result for the user, the slide tube mayhave a translucent or transparent design in sections, in particular inthe areas that are provided with the at least one screen module. Acrylicglass, for example, may be used for a transparent design.

However, a translucent, for example opaque, design may be preferred insome implementations, since this approach may allow, for example, onlythe pixels of the at least one screen module to show through and bevisible to the user, and the remaining module technology may remainconcealed. In particular materials such as glass-fiber reinforcedplastic (GFRP), polycarbonate, and Plexiglas may be suitable for atranslucent design.

Surprising synergistic effects may also result, in addition to the novelslide experience and the achievable optical effects. Due to integrationof the at least one screen module into a water slide system, good heatdissipation from the pixels, preferably composed of LEDs, may be ensuredin an innovative manner, such as when the pixels directly contact theouter side of the slide tube, i.e., lie against it on the outside. As aresult of the direct contact, heat may be released to the translucent ortransparent slide tube material. This material is in turn may be cooled,at least in sections, by the slide water present in the water slide orthe slide tube. The screen module (LED module/digital image area) maypreferably have the following minimum specifications: Flex displayand/or LED pixel pitch of 7 mm, and/or a pixel density ≧15,876 persquare meter, and/or a brightness >5000 nits, and/or a power consumptionof 250 W/m², and/or a viewing angle of 120°, and/or a refresh rate 1800Hz, and/or a moisture resistance 99%, and/or 16,000,000 colors.

Thus, a curved screen may thus be used, for example, to directlysurround the slide tube and may be cooled from the front side withwater.

Another desirable effect may include that water flow or water film,which from the user's viewpoint, may occur in front of the image, maybring about interesting streak effects that are intensified by suitableimages or distortion techniques, or may be at least partially becompensated for if needed.

Thus, one example water slide system designed according to thedisclosure may have a slide tube that is directly associated with acurved image area composed of a plurality of pixels arranged in a matrixin order to provide the user with numerous novel visual impressions. Anarrangement of pixels in a matrix is understood to mean, for example,that pixels may be situated along two axes that are spanned by an angle,in particular about 90°, one of the axes being curved in thecircumferential direction of the slide tube, in particular having aradius of curvature that corresponds to the radius of curvature of theslide tube. The pixels may be arranged in rows and columns and may beindividually actuated. The rows may preferably extend in parallel to theslide direction, while the columns of pixels may be orientedperpendicularly thereto, in order to follow the curvature of the slidetube in the circumferential direction or map the same, such as in astepped manner. To ensure an image, which may be curved in thecircumferential direction and which at the same time may further extendin two-dimensions and/or stereoscopically in the slide direction, isproperly viewable, the screen module used may have a shell-like design.This approach may be achieved in a particularly innovative manner byconnecting submodules (module surface sections) that may in each case beflat so that they extend, for example, in an articulated manner, in eachcase with two adjacent submodules enclosing an angle. With a preferredarticulated connection of submodules or partial screen sections of amodule, the module may be adapted to the individual radius of differentslide tubes in a particularly innovative manner.

As mentioned, the water slide system designed according to thedisclosure may include at least one, preferably shell-like, screenmodule suited for displaying curved two-dimensional images, for example,in the form of moving images (video). One embodiment of the water slidesystem may provide stereoscopic images that are displayable and/ordisplayed, for example, in the form of stereoscopic videos, on at leastone screen module, and in some implementations, preferably multiplescreen modules. In this way, a spatial impression of depth that is notphysically present (except for possibly the curvature) may be impartedto the user. The principle of stereoscopy is based on the fact that a(human) user observes his/her surroundings simultaneously from twoviewing angles through his/her two eyes. In this way, the brain of theuser is able to efficiently associate a distance with all objects beingobserved, or to obtain a spatial image of his/her surroundings, withouthaving to keep the head in motion. The stereoscopy, or in this specificcase the stereoscopic actuation, of the at least one screen module onlyallows different (in each case two-dimensional) images to be broughtinto the left eye and the right eye of the user from two slightlydifferent viewing angles. For this purpose, there are different methodsknown in the related art, but which have not been applied thus farwithin the scope of a water slide system. As explained in greater detailbelow, in one aspect, a shutter method, or alternatively athree-dimensional polarization system method, may be used, whereby, asexplained in greater detail below, the user may wear appropriate channelseparation features, such as glasses, while sliding. With this approach,images may be displayed simultaneously or in succession, depending onthe applied method, and viewed by the eyes separately, in a definedmanner. The screen module may be designed and actuated as a so-calledstereo display to allow stereoscopic vision for the user, depending onthe method, with or without channel separation aids, such as appropriateglasses (e.g., shutter glasses or polarized filter glasses).

In an aspect, the waterslide may include tubes having a circular orapproximately circular cross section or partial such cross section, forexample, having a diameter in a range between about 60 cm and 300 cm.Alternatively, it is also possible to use slide tubes having acircumferential contour that is different from a circular shape, forexample oval slides, in which case a maximum is preferably selected froma value range of about 60 to 350, and a minimum diameter, extendingperpendicularly thereto, is selected from a value range of about 50 to300.

In one embodiment, images may be displayable in different ways, forexample by changing colors using screen modules. This aproach may beachievable in a particularly innovative and simple manner by forming thepixels from multicolored light emitting diodes, such as two, three, ormore differently colored LEDs, as is basically known, for example, fromLED displays for large events.

In an aspect, the LEDs that are used within the scope of the screenmodule may be able to display a color spectrum of 16,000,000 colors ormore.

In one embodiment of a water slide system, at least one screen modulemay be connected in a signal-conducting manner to actuating features,which may include a video processor, for example, in order to supply thescreen module with a suitable actuating signal for displayingtwo-dimensional and/or stereoscopic, in particular multicolored, images.The actuating features may preferably be designed in such a way thatthey have a terminal for connection to an image source, such as a videosource, and/or are connected to an image source. The image source, inparticular video source, may be a media server, for example, or in thesimplest case may be a suitable playback device, such as a video player,preferably in the form of a Blu-ray player or a DVD player. The inputsignal, with the aid of the actuating features, is then converted into apreferably multiplexed control signal for actuating the screen module.

It is particularly advantageous when the water slide system comprisesmultiple screen modules, not just a single screen module. In an aspect,the multiple screen modules, for example, having a shell-like design ineach case, may be arranged adjacent one another sequentially in thecircumferential direction in order to thus cover a preferably largecircumferential angle, such as 120° or more, more preferably at least180°, and very particularly preferably at least approximately 360°.

In addition or as an alternative to an arrangement of multiple screenmodules in the circumferential direction, it is possible to arrangemultiple screen modules one behind the other in the slide direction.

It has been found to be particularly advantageous when the actuatingfeatures for actuating the screen modules include a video splitter withwhich multiple screen modules arranged next to one another in thecircumferential direction and/or one behind the other in the slidedirection so as to be actuatable or actuated for displaying a movingoverall image. Thus, image information provided by an image source(signal source) or video source may be divided over multiple screenmodules, such as in a matrix confirguration.

In an aspect, the multiple screen modules, having a shell-like design ineach case (analogously to the pixels of a screen module) may be arrangedin a matrix and thus form an overall screen that, as explained ingreater detail below, is preferably actuatable for displaying an overallimage.

In an aspect, the actuating features may be designed in such a way thatan image that extends over all pixels of a screen module and/or an imageportion that extends over multiple screen points (in particular arrangedin a matrix) may be displaceable from pixel to pixel and/or from screenmodule to screen module in the circumferential direction of the slidetube and/or in the slide direction and/or opposite the slide direction.In this manner, image content that is constant, in particular at leastwith regard to the image content contours, may be further displaced on ascreen module, such as beyond the module boundaries, in at least one ofthe above-mentioned directions or in a resultant, for example diagonal,direction from a plurality of the above-mentioned directions, thusimparting an impression of motion.

It is thus possible, for example, to further displace a serratedgeometry, extending in the circumferential direction, in the same oropposite direction as the slide direction and thus display a movementsequence. This approach may be particularly used, for example, when theabove-mentioned image content (or some other image content) repeats, andthe repetition as a whole is moved in the same or opposite direction asthe slide direction. It is also possible to further displace imagecontent, extending in the slide direction, in the circumferentialdirection.

As discussed above, in an example implementation, a shell-like screenmodule may be implemented that has multiple module surface sections thatinclude pixels arranged in a matrix in a shared straight plane.;Alternatively, the arrangement may include only single rows of pixelswithin two adjacent flat module surface sections enclosing an angle, sothat in the entirety of the module surface sections form a shell-likescreen module that extends around the slide tube in the circumferentialdirection results. In one embodiment of the screen module, the modulesurface sections may be articulatedly connected to one another, thusallowing simple adaptation of the screen module and different radii ofcurvatures of different slide tubes.

In some cases, each module surface section may include multiple pixelsarranged one behind the other in the slide direction, the entirety ofthe module surface sections or the pixels being arranged thereon in amatrix or in a row resulting in the pixel matrix of the screen module.

As discussed above, it is possible on the one hand to achieve an imagethat extends over the entire circumference of the slide tube. On theother hand, it is possible to achieve an image over only a partialcircumferential section of the slide tube by arranging at least onescreen module, or alternatively multiple screen modules next to oneanother, in the circumferential direction. In the latter-mentioneddesign, the circumferential angle section that is not occupied withscreen modules may have an at least partially, and preferably completelyor nearly completely, reflective design, for example by integrating areflective foil into the slide tube. In this way, a particularlycost-effective option is provided for producing an overall image thatextends, at least predominantly, over the entire circumference, sincethe images of the partial section occupied by screen modules reflect onthe reflective surface.

To ensure optimized heat dissipation of the pixels that are preferablyformed from LEDs, it has proven to be particularly advantageous when thepixels arranged in a matrix, in particular LEDs, lie directly on theouter side of the slide tube that is acted on by water, at least insections, on the inner side. In this way, the thermal conductivity ofthe water may be additionally utilized for the heat dissipation.

The water slide system may include wetting features, including at leastone pump, for wetting the slide surface. Various options may be used forwetting the slide surface. In an aspect, a visible water stream, forexample several millimeters in height, which flows along the slide tubemay be generated on the slide surface.

Additionally or alternatively, it is possible, at least in sections, togenerate merely a moisture film, for example by introducing moisture,e.g., water, via spray nozzles. This design may allow optimal cooling ofscreen modules situated, for example, in an upper tube section.

As discussed above, in one embodiment of the water slide system, thescreen module may be designed as a stereoscopic display, and beactuatable and/or actuated for the simultaneous or time-delayed displayof two different images, in particular differing with regard to theviewing angle of the displayed image contents, one for the left eye andanother for the right eye of a user, in order to achieve athree-dimensional visual impression. Appropriate stereoscopicallyprepared image contents may be provided by an image source, such as amedia server and/or a playback device. The slightly differing images,which in each case may be curved in two dimensions, possibly due to thepreferred screen module curvature, are then combined in the brain toform an overall image for the perception of depth.

In this regard, stereoscopic viewing methods that provide the necessaryseparation or association of a left- and a right image for the eyes maybe referred to as channel separation. As the result of appropriatedesign of the stereoscopic image information, optionally in conjunctionwith suitable channel separation features, for example polarized glassesand/or shutter glasses, it may be ensured that each eye is able to seeonly the image that is associated with it. One approach may includecomplete channel separation, in which the right image is completelyinvisible to the left eye, and vice versa. Another option, implementablewithin the scope of the water slide system of the present disclosure,which achieves a three-dimensional impression, may involve channelseparation using circularly polarized light, the user in this casepreferably wearing channel separation features in the form of polarizedfilter glasses. In the polarization process, images for the right eyeand the left eye are preferably displayed at the same time, the channelseparation features (polarized glasses) preferably allowing only everyother line of the image to pass through, thus distributing half-imagesto both eyes. In an aspect within the scope of the water slide system ofthe present disclosure is the use of alternative shutter technology. Inthis approach, the images for the left eye and the right eye aredisplayed in succession, with control pulses preferably being sent tothe channel separation features worn by the user, in particular, forexample, shutter glasses. Shutter glasses mutually darken the installed“glass” in each case, in particular an LCD glass, to ensure that eacheye sees only the image intended for it. It is also possible toimplement a color anaglyphic approach, for example. In order to separatethe two single images, preferably displayed at or near the same time,various color filters are used in the channel separation features (inparticular, for example, red-green glasses). Alternative stereoscopicapproaches are also usable, in particular those that do withoutadditional channel separation features to be worn by the user. Withthese approaches, the screen module may have multiple pixel planes, inparticular in the form of a so-called tensor display, which may beactuated with high refresh rates, such as at rates greater than 200 Hz,in particular 240 Hz or 360 Hz.

For some of the methods mentioned above, in particular the preferredshutter method and the preferred polarization method, it may benecessary for the user to wear channel separation features in an area infront of the eyes during the sliding operation. In the case of theshutter method, the channel separation features may be acted on by acontrol pulse that is synchronized with the display. For the specialfeature of a water slide system in which the user slides on a water filmon the slide surface in the slide direction, it has proven to beadvantageous when the channel separation features are securely anddetachably fixable to the head of the user, preferably by tensioningwith at least one elastic band and/or integrated into a helmet or aheadband or the like. Notwithstanding, it is very advantageous when thechannel separation features are designed in the manner of diving orswimming goggles, e.g., in such a way that the goggles are supported viasealing features, in particular an elastomeric material, on the head,about the area of the user's face, in order to avoid impairment of theimage perception, and in particular to provide a three-dimensionaleffect between the eyes and a translucent surface (in particulareyeglasses) of the channel separation features.

In this regard, reference is made to the use of channel separationfeatures, in particular in the form of glasses, preferably shutterglasses or polarized filter glasses, that are fixable, in particulartensionable, preferably on the head of the user, and/or use sealingfeatures for water-tight contact on the body, in particular on the headof the user, during sliding on a water slide having at least one screenmodule, in particular during use of a water slide system designedaccording to aspects of the disclosure.

Regardless of whether the screen module of the water slide system isdesigned and actuated for displaying images with a two-dimensionaleffect or images with a stereoscopic or three-dimensional effect,according to one example, it is advantageous for the system to have adetector for detecting, at specific points or consecutively orcontinuously, a position and/or speed (in particular sliding speed) ofthe user, and for the screen module to be actuatable and/or actuated asa function of the position signal and/or speed signal of the detector,for example, in such a way that two-dimensional or stereoscopic imagecontent, in each case in the form of a video, or alternatively, astationary image or, in the case of a stereoscopic display, stationaryimages, which change as a function of the position signal and/or speedsignal. In this way, particularly impressive effects may be achievedthat are a function of the individual position of the person slidingalong the water slide and/or of the person's speed. In one simpleexample implementation, the position may be detected using aphotoelectric barrier, for example. It is also conceivable to arrangemultiple photoelectric barriers (or other detection sensors) one behindthe other in the slide direction in order to obtain position informationand/or speed information that continues in a stepped manner.Alternatively, continuous position detection using suitable sensorfeatures, for example a camera, or alternatively, multiple cameras, maybe used.

The disclosure also sets forth a method for operating a water slidesystem designed according to various aspects of the disclosure.According to such aspects, it is provided that the at least one screenmodule is actuated in such a way that a moving image that is curved inthe circumferential direction and is visible from the interior of theslide tube is displayed by the pixels of the screen module arranged in amatrix. The image may be provided by an image source, for example, amedia server or a video player. The image may extend over multiplescreen modules, thus resulting in an overall, in particular moving,image.

In an aspect of the method, the screen module or multiple screen modulesmay be supplied or actuated for displaying a moving (video) overallimage, using stereoscopic images, to achieve a three-dimensional effectfor the user. Depending on the technology used, during the slidingoperation, the user may wear appropriate channel separation features(see the above discussion) or these may be provided to the user for useduring sliding. It has been found to be particularly advantageous whenthese channel separation features are worn fixed in position on thebody, e.g., may be detachably fixed to the body of the user, for exampleby tensioning using an elastomeric feature, such as an elastomeric band,or alternatively, the channel separation features may be equipped withsealing features for tight contact with the body, such as the head ofthe user, to prevent water from entering the area between the eyes, andthe translucent surface of the channel separation features.

DETAILED DESCRIPTION

FIG. 1 shows a section of a water slide system 1 that comprises a slidetube 2 made of translucent or transparent material. The slide tube 2, ina manner known in the related art, may be made up of multiple tubemodules 3 arranged one behind the other in a slide direction R, eachtube module 3 in turn being mounted from multiple, in the present case ashown, two, shells 4, 5, specifically, an upper shell 4 and a lowershell 5.

The slide tube 2 in its interior forms a slide surface 6 that extends inthe slide direction R. The slide surface 6 may be wetted with the aid ofwetting features 7. In the specific example embodiment shown, thewetting features 7 include a pump 8 that conveys a water stream in acircuit, the water being introduced in an upper slide area and collectedin a lower slide area, and then provided once again to the watercircuit.

It is apparent than a plurality of screen modules 10 may be situated onan outer side of the slide tube 2, illustrated here with a circularcross section by way of example, the screen modules each having aplurality of pixels (not illustrated), in the form of high-performanceLEDs. The LEDs may be arranged in columns and rows, e.g., in the form ofa surface matrix, the pixels being individually actuatable in order todisplay images, such as moving images.

In an aspect, each screen module may have a minimum number of 15,876LEDs (individual units) per square meter.

The screen modules 10 may optionally be curved only about an axis thatextends in the slide direction R, e.g., in the circumferential directionof the slide tube, and have rows of pixels arranged in parallel to theslide direction R. The columns, oriented essentially perpendicularlythereto, follow the curvature of the outer side of the slide tube.

The screen modules 10 with their pixels may rest on the curved outerside. It is apparent that the screen modules 10 may have a shell-likedesign, and in each case may extend over a circumferential angle ofgreater than about 45°, and over at least about 0.5 m in each case inthe slide direction R.

It is apparent from the arrangement according to FIG. 1 that a pluralityof screen modules 10, six in each case as shown in this specificspecific example embodiment, are arranged next to one another in thecircumferential direction. Screen modules 10 are also arranged onebehind the other in the slide direction R, so that by appropriatelysubdividing an original image, it is possible to divide it over theplurality of screen modules arranged in a matrix, so that all screenmodules 10 or a group of these screen modules 10 display an overallimage, which means that each of the screen modules shows an imagedetail.

In the specific example embodiment shown, in each case two adjacentscreen modules 10 in the circumferential direction and in each case twoadjacent modules in the slide direction are spaced apart from oneanother; one embodiment is also achievable in which the adjacent screenmodules in the circumferential direction and/or the screen modulessituated one behind the other in the slide direction R directly adjoinone another to thus allow a cohesive visual impression.

The shell-like design of the screen modules 10, curved in thecircumferential direction, is apparent in FIG. 1. This effect may beachieved in various ways. It is thus conceivable to use a curved LEDcarrier. Alternatively, as shown in FIG. 3, it is possible to use ascreen module 10 that has multiple module surface sections 11 a through11 c, in each case two adjacent module surface sections 11 a through 11c spanning an angle with respect to one another. The pixels, such asLEDs, of each module surface section 11 a through 11 c in each case mayspan a (straight or noncurved) plane. In the simplest case, each sectionof the module surface sections may have only a single row of pixelsextending in the slide direction R. However, each module surface sectionR may preferably have a plurality of such parallel rows extending in theslide direction R.

A design in which the module surface sections 11 a through 11 c arearticulatedly connected to one another in order for the module surfacesections to lie around the slide tube in the circumferential direction,essentially regardless of their diameter, is particularly advantageousin some implementations. Adaptation to different diameters is easilypossible due to the articulated connection.

In FIG. 1, screen modules 10, as mentioned, are arranged over the entirecircumference of the slide tube 2. An alternative embodiment, not shown,is conceivable in which only a partial circumferential section isprovided with screen modules 10. The slide tube may thereby have areflective design in the remaining section in order to give the opticalimpression that more screen modules are provided than is actually thecase. For example, it is conceivable to provide only the upper shell 4or only the lower shell 5 with screen modules 10, and to provide areflective design, at least in sections, for the respective other shell.

It is apparent from the schematic illustration according to FIG. 1 thatthe screen modules arranged in a matrix are actuated via actuatingfeatures 12, which may include, for example, a video processor. Theactuating features 12 may be supplied with an image signal, such as avideo signal, from an image source 13, such as a media server.

FIG. 2 shows a more detailed design of an example electronics systemusable in accordance with aspects of the present disclosure. The imagesource 13, which may be coupled to the actuating features 12 in asignal-conducting manner, may be located to the left in FIG. 2. Theactuating features 12 may include a video processor unit 14 (videoprocessor), which in turn is connected in a signal-conducting manner toa video splitter unit 15, which may divide an overall image over four,by way of example, screen modules 10. These screen modules 10 may bearranged next to one another in the circumferential direction or onebehind the other in the slide direction. FIG. 2 shows only the basicschematic design. Of course, the video splitter unit 15 may be designedin such a way that it supplies a curved matrix of screen modules 10, asshown in FIG. 1, for example.

In some example implementations, the screen modules may be supplied oractuated with stereoscopic images via the actuating features 12 forachieving a three-dimensional effect for the user, such as when anoverall image is achieved by appropriately actuating multiple screenmodules via the video splitter unit 15.

It may be advantageous in some implementations, when the detector (notillustrated) for detecting a position and/or a speed of the user isprovided, and the detector is directly or indirectly connected to theactuating features 12 in a signal-conducting manner, for the actuatingfeatures 12 to adapt or change image content as a function of a detectedposition and/or speed.

Aspects of the present invention may be implemented using hardware,software, or a combination thereof and may be implemented in one or morecomputer systems or other processing systems. In an aspect of thepresent invention, features are directed toward one or more computersystems capable of carrying out the functionality described herein. Anexample of such a computer system 400 is shown in FIG. 4.

Computer system 400 includes one or more processors, such as processor404 and a graphics processing unit 432, which may correspond to thevideo processor unit 14. The processor 404 is connected to acommunication infrastructure 406 (e.g., a communications bus, cross-overbar, or network). Various software aspects are described in terms ofthis example computer system. After reading this description, it willbecome apparent to a person skilled in the relevant art(s) how toimplement aspects of the invention using other computer systems and/orarchitectures.

Computer system 400 can include a display interface 402 that forwardsgraphics, text, and other data from the communication infrastructure 406(from the graphics processing unit 432 or from a frame buffer (notshown)) for display on a display unit 430.
